A method for analysis of a cell structure includes a macroanalysis step and a microanalysis step. The macroanalysis step includes replacing a cell structure or a part of the cell structure with an anisotropic solid body having property values of equivalent rigidity characteristics, creating a finite element model of the anisotropic solid body based on the property values, applying an internal temperature distribution or an external pressure to the finite element model of the anisotropic solid body, determining the stress distribution in the anisotropic solid body, and selecting an aimed cell structure of which the stress should be calculated as a cell structure based on the stress distribution. The microanalysis step includes creating a finite element model of the aimed cell structure, and determining the stress distribution in the aimed cell structure based on the finite element model of the aimed cell structure. The structural analysis method is a means for analyzing the stress distribution in the cell structure due to the internal temperature distribution or external pressure which can be realized by using general-purpose computer software and hardware without performing a simulation test and making a large investment.
